Demoutable barrier for premises
First Claim
1. A demountable barrier (8) for substantially preventing or minimising access of air and/or water into premises (2) through an access region (4) provided in a wall (6) of the premises, wherein the barrier (8) comprises:
- a frame member (10) adapted to be firmly secured to the wall of the premises and surrounding the access region, the frame member having a longitudinal channel (20) therein in a first face (22) thereof open towards the wall of the premises;
a resilient membrane (30) secured to the frame member and framed by the frame member and overlying and closing the longitudinal channel;
at least one non-return air valve means (28) extending to the longitudinal channel from a second face (24) of the frame member and sealed through at least one aperture provided in the frame member;
a compressible sealing member (38) adapted to be located between the frame member and the wall of the premises; and
pump means (40) to provide pressurised air into the longitudinal channel through the at least one non-return air valve means, to effect ballooning of the resilient membrane overlying the longitudinal channel and compression of the compressible sealing member, whereby a substantially water- and/or air-tight seal is effected between the frame member and the wall.

Abstract
A demountable barrier (8) for substantially preventing access of water into premises (2) through an access region (4) provided in a wall (6) of the premises. A frame member (10) has a longitudinal channel (20) in a first face (22) open towards the wall of the premises. A resilient membrane (30) is secured to the frame member and framed by the frame member and overlying and closing the longitudinal channel. A non-return air valve (28) extends to the longitudinal channel from a second face (24) of the frame member and is sealed through an aperture provided in the frame member. A compressible sealing member (38) is located between the frame member and the wall of the premises and pump means (40) provides pressurised air into the longitudinal channel through the non-return air valve, to effect ballooning of the resilient membrane overlying the longitudinal channel and compression of the compressible sealing member, whereby a substantially water-tight seal is effected between the frame member and the wall.
